Industrial Robots in PCB Industry?

Friday, November 30th, 2018

NowadaysÔľĆthe application of industrial robots in PCB¬†industry are in the stage of beginning and there are still lots of problems need to be solved. Many production lines in PCB¬†industry are non-standard products (the products and equipments are do not based on the unified industry standards and specifications published by the country, but designed and fabricated by oneself according to one‚Äôs own needs).

However, there is still a long way to go to apply robots in the printed circuit board industry. Because the robots are limited by the existing working space and the ability of the original equipments in the process of application. Meanwhile, confronted with the application of various sensors to improve the intelligence of robots. All these factors influence the large-scale application of robots in PCB industry.

Although there are still some difficulties stuck the application of industrial robots in PCB industry, applied the robots into the PCB industry still have a bright prospect. The robots applied into the PCB industry will show a trend in the future as following:

  1. From single line application to multiple line application, the PCBmanufacturer need to invest a lot of money if they would like to introduce the robots to realize automated production. But they can expand the scale of application gradually after reforming the existing single line.
  2. From the application of simple robots to the application of AGV (Automated Guided Vehicle) combined with other intelligent devices, most of the material transfer between existing production lines is manual operation, which can be distributed by the combination of robots and AGV to achieve orderly material transfer.
  3. The application of robots in the original factory should be localized. But if the new plants need to realize automated production in full aspects, it means that introducing the application of robots and AGV is required.
  4. Get the process of manufacturing more intelligent and more flexible by the combination of industrial robots and IoT (Internet of Things).

Since throwing its hat into printed circuit board industry, Best Technology always tries its best to adopt the most advanced equipment to make rigid circuit board, rigid-flex circuits, ceramic PCB etc. with high quality for our clients. Choose us, you deserve the most suitable products and the most satisfying service at a good price. More information, please check our website: https://www.bestpcbs.com

Customer Oren and Amitay from Israel visited our company

Friday, October 14th, 2016

On Oct 14th, customer Oren and Amitay from Israel visited our company. They are very nice and smart, just arrived at our office without any more instruction. We’re old friends since 2011 but never meet each other in China. After drinking Chinese black tea, we had a delicious lunch: Chinese traditional Hot Pot and fried fish with red pepper.

We also took photo with some of sales girls in office. You can see, how happy we are!

After that, they visited our Printed Circuit Board factory to visit whole PCB manufacturing process. From initial PCB raw material cutting, CNC drilling, exposure, etching, copper platting, soldermask & silkscreen printing, CNC routing, V-cutting, to final opening & shorting testing, flying probe testing, FQC and packaging. We also introduce our special board such as heavy copper PCB, extra thin PCB.

After visiting whole process of FR4 Printed Circuit board and Metal Core PCB, they speak highly of us and also give us some suggestion to help us to improve our PCB manufacturing level and PCB quality. Thank you Oren and Amitay.

Looking forward to seeing you soon in Israel in 2017.

Why Soldermask Opening or Tented was not the same like the Original Gerber file?

Monday, August 29th, 2016

Recently customer compliant that the soldermask for some holes, esp for PTH (plated through hole, sometimes people named Via) was wrong, because in his original Gerber file, it was opened, but on actual printed circuit board, it was tented (covered), and some cases, some was tented and some was opened at the same time. It made customer confused.

In fact, there’s a default rule in PCB (printed circuit board) manufacturing: If the PTH (Via) was less than 0.60mm, then the soldermask will be made as per factory’s default rules: making them as tented (covered), regardless it was tented or opened in customers’ original Gerber file.

Here you can see pictures showing a board with a 0.30mm PTH, soldermask was opened in original Gerber file, but in real board, it was tented.

0.3mm Via soldermask

0.3mm Via soldermask

And in this board, for 0.508mm PTH (via), some soldermask was opened and some was opened.

0.508mm Via soldermask

0.508mm Via soldermask

Why like that? Here are two major reasons:

1) For PTH(via) less than 0.6mm, normally the function was only to electrically connected trace, not for electronic components assembled; so whatever PTH was opened or tented, it doesn’t matter.
2) In rigid printed circuit board manufacturing, it’s not easy to etch away the soldermask around PTH less than 0.60mm. As soldermask was made by that method: printed whole area with oil (soldermask), then undergo develop & exposure, then pass the etching line. The chemical will etch away the oil accordingly to the drawing, but if the hole was too small (less than 0.60mm), then the oil around will be very difficult to etch away, so you will see some oil was etched away (soldermask opened), some oil still here (soldermask tented)

If diameter of hole was bigger than 0.60mm, then it’ll be easy to etch away and some of them will be used in assembly, so we will make according to Gerber file and you will see the board exactly like the drawing. See bellowing a picture showing a board with 0.889mm (0.035mil) PTH.

Sometimes, people just use these hole as testing point, not for assembly, then we suggest to add another PAD connected to this hole so that you can test it easy. To tested on hole was not stable as tested on a PAD.

In a conclusion, in future, if the hole was less than 0.60mm and you really want it to be opened, please add special notes when release order, and allow us to enlarge the opening diameter of soldermask (around 0.60mm) so that soldermask of these holes will be opened.

Please contact us if still any question about soldermask opening.

Bigger size of Ceramic PCB is Available Now!

Wednesday, December 10th, 2014

Good news! This month we have used a new machine which can print much bigger size of silver palladium, Gold palladium, and glass glaze on Thick Film Ceramic PCB.

Currently the normal dimension in thick film Ceramic PCB is about 80 x 138mm and that size has already limited a lot of designs. You can’t put too much trace, PAD on such smaller size board, and the you have to use 2 layer, or 4 layers ceramic board to put more trace. And of course, that will increase a lot of cost definitely!

Now, we can make 200 x 200mm (8×8 inch). Thinking about the normal 80x138mm and you will find out this is an extreme improving! See bellowing pictures show the comparing!

So now you don’t need to worry about the size! You can design as big as you want!

And we are also continuing to adopt first-of-art machine and technology to make bigger size, higher quality Ceramic PCB!

Please contact us if you have more good idea, or suggestion about Ceramic PCB.
